Hi all!
I got this nice idea today to do a apt-get update/upgrade on my system.
when it was done I moved the box, and upon reboot my lvm was gone. I
think I had lvm1 before, but now it seems like I have
LVM version: 2.00.29 (2004-11-27)
Is this maybe what is causing the problem?
My lvm is at /dev/volume_group/mylv, my lvm consisted of hde,g,i
I noticed from dmesg that
LVM version 1.0.5+(22/07/2002) module loaded
and that devfs wouldn't be started... (no volumes or equiv)
Please advice, I got pretty much schoolwork on it...
Daniel

Known issues with Debian:
lvm.conf detect_md_component should be set to 1 not 0
lvm.conf filters - check if cdrom drive is excluded correctly:
sometimes the cdrom exclusion points to a real hard disk by mistake
Use pvscan -P to check what LVM2 actually sees.

lvm.conf and cdrom exclusion: checked and confirmed
pvscan -P gives me the following(scroll down). Seems ok for actual
devices (/dev/hdb,f,h,j does not exist)
I am currently in status of what is described in thread "Can't mount
after crash"

Have you tried booting with the old kernel and old initrd?
